C# 获取QQ群数据的实现-白红宇

一,分析

1,群数据获取

当访问我们通过Fiddler可以查看到QQ群列表是从这个URL获取到的群列表信息

其中返回的json数据,json构成如下

从上面我们可以看出c包含的是群列表信息,r包含的是服务器的信息,其中c的某一项构成如下图所示

从上面可以看出项名称就是群号,owner为所有者,name为群名称,memo群描述,brief为群公告信息,还有其他的一些信息,大家自己去匹配,我这里就不一一解释了.

2, 单个群的成员获取,在上面我们分析了如何获取群列表,下面我们将分析如何取得单个群成员的数据

当我们点开某个群可以看到有查看通讯录的选项

此时我们通过Fiddler监视可以发现,群成员信息,通过如下地址取得

但是我经过几次点击测试,发现URL参数规则如下

贴出参数构造规则

const string groupMemberUrl = "http://qun.qq.com/air/{0}/addr/index/type/1/p/{1}?w=n&_={2}";

string memberURL = string.Format(groupMemberUrl, gInfo.Number, page, JavascriptAction.Random());

我们按照这样的地址去请求,就会得到QQ群成员的HTML,然后我在解析HTML就可以得到相应的数据了

二,实现

1, 获取群列表

public List
     
       GetGroupInfos()

if (!isLogin) Login();

List
     
       giList = new List
      
       ();

string json = GetWebData
     
      (string.Format(groupListUrl, JavascriptAction.Random()));

try

var jsonObj = JavaScriptEngine.Run("var m=" + json + ";m.c") as Dictionary
     
      ;

foreach (var key in jsonObj.Keys)

var gi = (jsonObj[key] as Dictionary
     
      );

if (!gi.ContainsKey("owner")) continue;

string owner = gi["owner"].ToString();

string name = gi["name"].ToString();

string max_member = gi["max_member"].ToString();

string create_time = gi["create_time"].ToString();

string notice = gi["brief"].ToString();

string number = key;

string memo = gi["memo"].ToString();

giList.Add(new GroupInfo()

CreateTime = JavascriptAction.GetTimeByJsTime(Convert.ToInt64(create_time)),

MaxNumber = Convert.ToInt32(max_member),

Memo = memo,

Name = name,

Notice = notice,

Number = number,

Owner = owner

});

catch { }

return giList;

上面的函数实现了群列表的获取,需要说明的是获取到的json是同过javascript引擎来运行的,javascript运行我通过Javascript .NET()来实现的,获取web数据参考我的blog的另外的文章,文章有实现源代码,至于登陆我最后会说明

2, 获取群成员

public List
     
       GetMemberInfo(GroupInfo gInfo)

if (!isLogin) Login();

List
     
       gmis = new List
      
       ();

int page = 1;

int pageCount = 0;

GETMEMBER:

string memberURL = string.Format(groupMemberUrl, gInfo.Number, page, JavascriptAction.Random());

string html = GetWebData
     
      (memberURL);

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();

doc.LoadHtml(html);

if (pageCount < 1)

var seeBtn = doc.DocumentNode.SelectSingleNode(pageBtnPath);

pageCount = Convert.ToInt32(seeBtn.Attributes["allpage"].Value);

var trs = doc.DocumentNode.SelectNodes(memberTrPath);

foreach (var tr in trs)

var tds = tr.Descendants("td").ToList();

if (tds.Count < 1) continue;

string groupNick = tds[1].Element("a").InnerText.Trim();

string qq = tds[2].Element("span").InnerText.Trim();

gmis.Add(new QQGroupMemberInfo()

NickName = groupNick,

QQ = qq

});

if (page < pageCount)

page++;

goto GETMEMBER;

return gmis;

上面的函数实现了群成员的获取,其中HTML的解析式通过HtmlAgilityPack()来实现,HtmlAgilityPack通过XPATH语法去解析实现的,关于xpath不是很难,大家查查资料就会了

3,关于登陆的实现

QQweb端的登陆有两种实现,第一种是web登陆,通过这样的URL实现来实现登陆,具体的实现原理,我前面有文章描述过了,这里就不罗嗦了,把类贴出来供大家参考

public class LoginQQ : WebPageAction, ILogin, IValidateCodeAction

static JavaScriptEngine _javaEngine = new JavaScriptEngine();

static bool _isInitJava = false;

Random _r = new Random();

const string loginFormUrl = "http://ui.ptlogin2.qq.com/cgi-bin/login?link_target=blank&appid=15000101&hide_title_bar=1&s_url=http%3A%2F%2Fim.qq.com%2Floginproxy.html%3Flogin_level%3D2&f_url=loginerroralert&target=self";

private User User { get; set; }

string _qq = "";

public LoginQQ(CookieManager cookieManager, User user)

: base(user.UserName)

_cookieManager = cookieManager;

User = user;

_qq = user.UserName.Split('@')[0];

if (!_isInitJava)

_javaEngine.Run(System.IO.File.ReadAllText(@"JavaScript\qq\md5_3.js"));

_isInitJava = true;

public override JavaScriptEngine JavaScriptEngine

get

return _javaEngine;

set

_javaEngine = value;

string vc_type = "";

public bool Login(string referer)

DateTime beginTime = DateTime.Now;

string html = "";

html = GetWebData
     
      (loginFormUrl);

if (!regForm.IsMatch(html))

ThrowException(507, html);

var form = GetFormDataByFormHtml(regForm.Match(html).Value);

string url = "http://ptlogin2.qq.com/check?uin=" + _qq + "&appid=15000101&" + JavascriptAction.Random();

html = GetWebData
     
      (url, referer: loginFormUrl);

string vcode = "";

if (html.Contains("ptui_checkVC('1','"))

vc_type = html.Replace("ptui_checkVC('1','", "").Replace("'", "").Replace(")", "").Replace(";", "");

form = new NameValueCollection();

if (!ValidationImageCode(form, loginFormUrl)) { return false; };

vcode = form["verifycode"];

else if (html.Contains("ptui_checkVC('0','"))

vcode = html.Replace("ptui_checkVC('0','", "").Replace("'", "").Replace(")", "").Replace(";", "");

TimeSpan _tspan = TimeSpan.FromTicks(DateTime.Now.Ticks - beginTime.Ticks);

if (_tspan.Seconds < 20)

Thread.Sleep(TimeSpan.FromSeconds(_r.Next(20 - _tspan.Seconds, 30)));

string pMd5 = GetPwdString(User.Pwd, vcode);

string action = "0-0" + "-" + (JavascriptAction.GetTime(DateTime.Now) - JavascriptAction.GetTime(beginTime));

url = "http://ptlogin2.qq.com/login?u=" + _qq + "&p=" + pMd5 + "&verifycode=" + vcode + "&aid=15000101&u1=http%3A%2F%2Fim.qq.com%2Floginproxy.html%3Flogin_level%3D2&h=1&ptredirect=0&ptlang=2052&from_ui=1&dumy=&fp=loginerroralert&action=" + action + "&mibao_css=";

html = GetWebData
     
      (url, referer: loginFormUrl);

if (html.Contains("登录成功"))

return true;

return false;

private string GetPwdString(string pwd, string vcode)

string script = "md5(md5_3('" + pwd + "') + '" + vcode + "')";

return JavaScriptEngine.Run(script).ToString();

public bool ValidateLogin(string referer)

var cks = _cookieManager.GetCookies(new Uri(referer).Host);

if (cks["uin"] != null && cks["skey"] != null)

return true;

return false;

public bool ValidationCode(string code, string referer)

return true;

public Image GetValidateCode(string referer)

string url = "http://captcha.qq.com/getimage?aid=15000101&r=" + JavascriptAction.Random() + "&uin=" + _qq + "&vc_type=" + vc_type;

return GetWebData(url, referer: referer);

public bool ValidationImageCode(NameValueCollection customFormItems, string referer)

ValidateReturn code = null;

do

Image image = GetValidateCode(referer);

code = this.FireValidateCode(image);

if (code.IsCancel)

return false;

if (customFormItems.AllKeys.Contains("verifycode"))

customFormItems.Remove("verifycode");

customFormItems.Add("verifycode", code.Code);

while (code.IsChange || !ValidationCode(code.Code, referer));

return true;

第二种就是从客户端点击,如QQ空间按钮,客户端会调用浏览器跳转

这样的地址,通过这个URL实现登陆,那么我们只需要HOOK ShellExecuteExW这个入口点就可以实现URL的截取,关于钩子如何实现,我前面有文章已说过,同样贴上代码供大家参考

public class ClientQQWebction : WebPageAction, IDisposable

const string loginUrl = "http://ptlogin2.qq.com/jump?ptlang={2}&clientuin={0}&clientkey={1}&u1={3}";

const string getEmail = "http://accountadm.qq.com/cgi-bin/account/ajaxgetmail?uin={0}";

const string groupListUrl = "http://qun.qq.com/air/group/mine?w=a&_={0}";

const string groupMemberUrl = "http://qun.qq.com/air/{0}/addr/index/type/1/p/{1}?w=n&_={2}";

const string pageBtnPath = "//input[@type=\"button\" and @value=\"查看\" and @act=\"gotopage\"]";

const string memberTrPath = "//table[@class=\"addressList\"]/tr";

CleintKeyInfo _cleintKeyInfo = null;

bool isLogin = false;

public ClientQQWebction(CleintKeyInfo cki)

_cleintKeyInfo = cki;

private void Login()

string loginURL = string.Format(loginUrl, _cleintKeyInfo.ClientUin, _cleintKeyInfo.ClientKey, _cleintKeyInfo.PtLang, string.Format(getEmail, _cleintKeyInfo.ClientUin));

var loca = GetWebData
     
      (loginURL);

if (_cookieManager.GetCookies("qq.com")["skey"] != null)

isLogin = true;

return;

throw new Exception("登陆失败");

public string GetEmail()

if (!isLogin) Login();

string emailUrl = String.Format(getEmail, _cleintKeyInfo.ClientUin);

var html = GetWebData
     
      (emailUrl);

if (regEmail.IsMatch(html))

return regEmail.Match(html).ToString();

else

return null;

public List
     
       GetGroupInfos()

if (!isLogin) Login();

List
     
       giList = new List
      
       ();

string json = GetWebData
     
      (string.Format(groupListUrl, JavascriptAction.Random()));

try

var jsonObj = JavaScriptEngine.Run("var m=" + json + ";m.c") as Dictionary
     
      ;

foreach (var key in jsonObj.Keys)

var gi = (jsonObj[key] as Dictionary
     
      );

if (!gi.ContainsKey("owner")) continue;

string owner = gi["owner"].ToString();

string name = gi["name"].ToString();

string max_member = gi["max_member"].ToString();

string create_time = gi["create_time"].ToString();

string notice = gi["brief"].ToString();

string number = key;

string memo = gi["memo"].ToString();

giList.Add(new GroupInfo()

CreateTime = JavascriptAction.GetTimeByJsTime(Convert.ToInt64(create_time)),

MaxNumber = Convert.ToInt32(max_member),

Memo = memo,

Name = name,

Notice = notice,

Number = number,

Owner = owner

});

catch { }

return giList;

public List
     
       GetMemberInfo(GroupInfo gInfo)

if (!isLogin) Login();

List
     
       gmis = new List
      
       ();

int page = 1;

int pageCount = 0;

GETMEMBER:

string memberURL = string.Format(groupMemberUrl, gInfo.Number, page, JavascriptAction.Random());

string html = GetWebData
     
      (memberURL);

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();

doc.LoadHtml(html);

if (pageCount < 1)

var seeBtn = doc.DocumentNode.SelectSingleNode(pageBtnPath);

pageCount = Convert.ToInt32(seeBtn.Attributes["allpage"].Value);

var trs = doc.DocumentNode.SelectNodes(memberTrPath);

foreach (var tr in trs)

var tds = tr.Descendants("td").ToList();

if (tds.Count < 1) continue;

string groupNick = tds[1].Element("a").InnerText.Trim();

string qq = tds[2].Element("span").InnerText.Trim();

gmis.Add(new QQGroupMemberInfo()

NickName = groupNick,

QQ = qq

});

if (page < pageCount)

page++;

goto GETMEMBER;

return gmis;

public void Dispose()

_cookieManager = null;

JavaScriptEngine = null;

OK,到此完成,下篇实现qq好友数据获取
